I made this GDM for LinuxMint, and this is the first GDM I have ever attempted to make, so I started with one already made, that I felt suited what I wanted to make it for. The original is called Relaxing Green, by FiremanSam, and can be found in his Complete green theme pack here http://www.gnome-look.org/content/show.php/Complete+Green+Theme+pack?content=66491
I take credit only for modifying his original theme and code, as I said this is the first time I have tried to make a GDM, so I wanted to start slowly, I give all credit for the original images and coding to FiremanSam.
That being said, I am going to start working on a new one, completely from scratch, but want to see what others think of this first attempt. Please leave comments and tell me whaat you think.
